To'aZZ to ho???) it may concern:

Be it known that I, JOHN A. OLBoN' a citizen of thell nited States,residing at Pat erson; in the county. of Pass-aic and State of NewJersey, have invented certain new and This invention relates toimprovements in.

steering post locks. I An important object of the invention is toprovide means whereby the steering wheel of an automobile may be lockedin order to prevent theft of the machiiie during the owners absence. i Vs A further object is to provide-such a lock of neat appearance andwhich will not detract from the appearance of the machine;

A further object is to providesuch a lock having means to prevent thelocking bolt from coming into engagement due to jar or vibrationiof themachine during'the driving thereof. s

Otherobjects and advantages will be apparent throughout the course ofthe following description;

In the drawings wherein for the purpose of illustration is shown apreferred embodimerit of my inventiomand wherein likenunierals'designate like parts throughout. Figure l is a sideGlGYEtlllOll O'fi an automobile steering wheel and post and having .mylock attached thereto Fig.2 is an enlarged longitudinal sectiontherethrough; F

Fig. 3 is: a perspective of the lock shown in Fig. 1, takenfroni theunder side thereof. Fig. 4 is a transverse section through the lock. o

Fig. 5 is a perspective casing. I i Fig. 6 is a perspective view of theplate which is attached to the steering post of the machine.

Fig. 7 is a bottom plan view of the lock, and i Fig. 8 is a perspectiveof the bolt drawing member of the lock.

Referring now more particularly to the view of the lock drawings thenumeral 10 indicates the steering "post of an automobile having securedto the upper end thereoef' a steering wheel 11. Surrounding the postist-he usual steer ng post casino- 12. 4 A "pair of complementary locksecticns i b withand 14 are provided hinged together as at 15. Thesections 13 and 14 are provided centrally thereof, with vertical curvedportions 16 and 17 which combine to forman opening adapted for thereception of 'the steering post casing 12; These sections when clampedabout the casing grip the cas iiig tightly V I The plate 13 has aportion 18 forming one wall ofthe lock casing propen' This wall has sidewalls 19, 20iand' 21outstanding therefrom and coasting with a wall 22forming a' portion of the section 14 to complete the lock casing. Thewall of plate 22 is provided with an outstanding lug 22", having anopening 23 formed therein. This opening is adapted to coact with anopening 24: formed in the wall 20 to receive a pin 25 to'hold thesections 13 and 14 in'closed rela tion The lug 22 is also provided witha vertical opening 26 which alines with an opening 27 formed in theplate 19. These openings slidably receive a locking bolt 28.

The sections 13 and 14 are provided upon then-upper ends withsemicircular flanges 29 and 30 respectively. These flanges are providedwith complementary receses 31 and openings 26 and 27 when the casing isassembled to, slidably receive the locking bolt 28.

' A circular plate adapted to be secured to the steering post isprovided, this plate comprising complementary sections 35 and 36 havingcentral recesses 37 and 38 respectively which coact to form an openingadapted to receive the steering post 10. Upon their upper surfaces thesections 35 and 36 are provided with upstanding flanges 39 and-10 whichare adaptedto receive the hub 48 of the steering wheel 11. The hub issecured tothe flanges by means of pins49 or the like. The sections 35'and 36 are provided with the depending flanges 41 and 42. These flangesextend over plates or' sections 29 and 30 when the lock is assembled onthe steering '55 tated by the key the bolt iswithdrawn and wheel andprevent insertion of a sharp edged'tool forv prying the lock open.'Thej' sections are hinged together a's'at 43' and: are

7 the sections are in the assembled position to receive a pin 4;?forcsecuring them in such assembled position, the plate 361s providec 1nits under side with a recess 50 which is adapted to receive the upperend or the bolt' 28 to lock the plate and steering wheel. to

the lock casing. As clearly shown in Fig. 2 the flange formed by thecomplementary flanges 4:1 and 42 engages against the outside oftheflange formed by-the sections 29 and 30; It is to be noted that, theinner portions 01" the plate engageunder the hub of steering Wheel andare consequently'held against ve'rtiealidlsplacement. w 7

" Mounted about the bolt 28 1s a compression spring 51 which extendsintermediate the lug 22 and a pin 52 extending transversely through thebolt 28. This spring normally projects the bolt for'engagement with theopening in the plate secured to the steering wheel. The lower end of thebolt 28 is round- I ed as at 55 and the bolt is provided with adjacentsuch rounded end with an annular 1 until the latch is released.

groove 56; The plate 21 is provided with the opening 57 through whichthe end of the bolt extends when in withdrawn position. Pivotedupon theplate 21 as at 58 isa latch member 59. Upon the plate 22 is provided ascrew '60 about which is mounted a spring 6l, one end'of whichengages-the latch forcing it into engagement with a lug 59 formed uponthe plate'21. By inspecting Fig. 3 it will be seen that when the latchis in this. position it extends partially over the opening 57. If thebolt is withdrawn the rounded head forces the latch member to one sideand the spring returns the latch to engage in the groove56. A thumbpiece 62 is provided upon, the latch wherebythe-bolt may be released. V

.1 The plate 18 is provided with an outstanding portion 63 having a bore64 adapted to receive a lock 65. The lock 65 has the. usual rotatablekey operated member 66 to which X that the bolt as soon as completelywithdrawn is locked in positionby the latch 59. s It is now immaterialwhetherv the. key is. withdrawnor not, asthe' bolt cannot move upwardlyfor engagement in the opening-50 As many changes are possible the shape,
